ATTACHING AND RETAINING- MEANS FOR VESTIBULE-DIAPHRAGMS AND THE LIKE.

` Application filed September 13, 1915.

To all whom t may concern:

Be it known that I, HARRY H. SCHRorER, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Attaching and Retaining Means for Vestibule-Diaphragms and the like; and I do hereby declare that the following is a full, clear, and exact description of the sarna-reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

Most types of car diaphragme are constructed of flexible material generally a heavy ply fabric secured upon the end of a car and to a face plate which is. adjustable to and from the end of the car, and is adapted to abut against a similar face plate on another vestibule diaphragm of another car when' the cars are coupled together. Dificulty has been experienced in properly securing the heavy ply fabric to the vestibule face plate as well as to the end of the car in a simple, convenient and eilicient manner, and it is the purpose of this invention to provide a retaining or attaching means by which the fabric of the diaphragm may be readily secured in place.

It is an object therefore of this invention to construct an attaching retaining means for fabric comprising a sheetA metal strip bent to form, permitting attachment of the strip to a support to clamp the margin of the fabric securely thereon without necessitating the attaching means for the strip engaging through the fabric.

It is also an object of this invention to provide an attaching and retaining means to secure fabric to a support whereby the retaining means may be loosened'without necessitating entire detachment thereof from the support to permit insertion or removal of fabric.

It is-also an object of this invention to construct a retaining means for a material adapted to hold the same without necessitating insertion of any mechanisms therethrough and in a manner to permit a slight sliding movement thereof if so desired.

It is furthermore an important object of this invention to provide an attaching means for flexible members of a vestibule to a car end and face plate comprising metallic strips Specification of Letters Patent.

. 4fabric of 'other modified form of Patented Mar. 20, 1917. Serial No. 50,322.

formed to secure the fabric in close relation on the car and face plate and permitting removal and replacement thereof without necessitating entire detachment of the retainmg or attaching means. v

It is finally an object of this invention to construct an improved type of retaining means capable of clamping an article sercurely in place and permitting insertion and removal of the article without necessitating entire detachment of the retaining means.

The invention (in a preferred form) is illustrated in the drawings andq hereinafter more fully describe On the drawings:

Figure l is a fragmentary central vertical section taken through a car diaphragm illustrating the attaching means therefor.

Fig. 2 is a detail section taken on Vline 2-2 of Fig. 1.

Fig. 3 is a detail section taken on line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail section illustrating the association of the attaching and retaining means with the car and with the the diaphragm.

Fig. 5 is a view similar to Fig. 4, of a modiied form of device.

Fig. 6 is a view similar to Fig. 4, of andevice.

As shown on the drawings:

The reference numeral 1, indicates the end of a car and the reference 2, the face plate of a vestibule diaphragm, and connected therebetween by means embodying the principles of my invention is a flexible fabric or other material forming the folds of the diaphragm of which the leg sections are denoted by the reference numeral 3, and the top section as a whole by the reference numeral 4. As shown in the detail section .in Fig. 2, the, top section 4, is substantially of U-shape, concave outwardly and inclined upwardly from the leg sections 3, toward the middleat a point Where the fabric is folded and stitched affording a rib 5. The

. upper portion of the leg sections 3, which are integral with the top portion 4, as clearly shown in the sectional view in Fig. 3, are of'i and at the tions consist of a metal strip which is used along the margins of the interior of the leg sections 3, denoted as a whole by the reference numeral 7, and on the exterior of the margins of the top section 4, denoted in the latter instance by the reference numeral 8. Fig. 4, is a typical section of the attaching means 7 and 8, which, as shown, comprises a strip of metal, the outer margin of which is bent inwardly at a right angle as denoted by the reference numeral 9, and the inner margin of which is folded inwardly in parallel relation with the main portion of the strip as denoted by the reference numeral 10, so that when used, the bent margin 9, abuts against the surface of the support 1 or 2, as thecase may be, and the inwardly turned margin 10, is spaced therefrom permitting insertion therebeneath of the margin of the fabric of the vestibule diaphragm.

The edge of the fabric is foldedver and stitched as designated by the reference numeral 11, thus affording an abutting edge for the inner edge of the inturned portion 10, which acts to prevent the fabric being withdrawn from beneath the retaining strip. Of course, however, the inwardlyV folded portion 11, could be omitted and the material merely clamped on the support by the retaining means. The metallic" adjusting means is secured upon the supports 1 or 2, as thecase may be, by means of bolts or lag screws or any other .suitable means designated by the reference numeral12, but as shown, comprising a bolt threaded into the support 2, through apertures provided in the strip or attaching means, whereby the same is drawn tightly and closely to the sup port clamping the margins of the fabric beneath the inturned margin 10. Furthermore the attaching screw or bolt 12, is so disposed as to engage through the attaching strip and into the support without passing through the fabric held in place thereby, and, as a consequence, if it becomes necessary to remove the fabric for replacement or repair, it is only necessary to loosen thel bolts or screws 12, thus loosening the retaining strip and permitting withdrawal of the margin of the fabric held in place thereby. A double retaining effect is gained due to 'the fact that the retaining strip is clamped securely against the support upon the fabric and furthermore, due to the fact that the inwardly folded portion of the fabric abuts against the inwardly turned portion 10, of the retaining strip thus assisting in preventing withdrawal of the margin of the fabric from beneath the retaining strip.-

In the modification illustrated in Fig. 5, l have shown' a supplementary strip 13, of fabric, metal, wood or the like, secured in any suitable manner on the margin of the material 3, to co-act with the inturned portion 14, of the retaining strip.

In F ig. 6, l have illustrated another modification wherein l utilize a retaining strip similar to that shown in Fig. 5, but with the material provided with a bead 15, integral therewith or secured thereon and of any suitable material for the purpose. ln all the constructions shown, however, the margin of the diaphragm material may be held strip of material having a folded margin, of p a metal strip, one margin thereof bent at an angle to contact a support, the other margin folded inwardly affording a space between the same and the support to receive the material threaded therebeneath and adapted to abut the inwardly folded portions of the material to prevent withdrawal thereof, and

'means attaching said metal strip to the sup port to clamp the material thereon and prevent withdrawal therefrom.

2. ln a device of the class described the combination with a support and material for attachment thereon, said material having an inturned margin, of a strip one margin thereof bent at an angle thereto to abut against the support, the other margin thereof turned inwardly to receive the material inserted between the same and said support and adapted to contact the inturned portion of the material, and means adapted to attach said strip upon the support without engagement through the material.

3. In a device of the class described the combination with a support and material for attachment thereon, the margin of said material turned inwardly, of an attaching strip comprising one portion turned inwardly for contact with a support, the other margin turned inwardly and spaced from the support permitting insertion of the material therebeneath to .abut against lthe inturned portion of the margin of said material, and means engaging through said strip and into said support to clamp the same securel,v thereon without engagement through the material.

4f. In a vestibule diaphragm of the class described the combination with a support and the fabric folds. of the diaphragm,

vmeans attaching the ,same upon the support comprising a strip, one margin of said strip turned at a right angle to abut against the support, the other margin of said strip turned inwardly into parallel relation therewith permitting insertion of vthe material therebeneath, and means attaching said strip upon the support to clamp the Vmaterial beneath said latter inturned margin thereof.

5. In an attaching and retaining means of the class described a strip, one margin thereof turned at a right angle to abut against a supportl` the other margin thereof turned in- Wardly therebcneath to receive a material inserted therebetween and the support, means on said material projecting above the surface thereof adapted to be contacted by said last mentioned margin, and means providing attachment on said strip for the support to permit loosening of said strip to permit insertion or removal of the material Without entire detachment of the strip from the suport. p 6. In a device of the class described the combination With a support and fabric to be attached thereto, the margin of said fabric turned inwardly and stitched thereto, of an attaching strip adapted to abut against the support at one side and spaced therefrom at the other side thereof permitting insertion of the fabric therebeneath' and adapted to abut against the inturned portion of the fabric to resist Withdravval therefrom and means securing said strip 'detachably to the support permitting insertion and removal of the fabric Without entire detachment of the strip and adapted, when tightened, to clamp the material to the support.

"7. In a device of the class described the combination with a su )port and material to be secured thereto, or a strip, the margin thereof turned inwardly to iermit insertion ofthematerial therebeneatli, said material having an inturned margin to abut against Y 9. In a device of the class described the combination with a support, of a diaphragm section to be connected thereto, an abutment member on said diaphragm section, and meansreleasably secured on the support contacting said diaphragm section engaging over the abutment thereon to retain the same associated with the support.

In testimony whereof I have hereunto subscribed my name in the presence of two' subscribing Witnesses.
